The Big Ten now has a season-high six ranked teams, including two in the Top 10 and four in the Top 15, at least in the coaches' poll.
Penn State re-joined the Top 25 after beating Iowa and improving to 5-1 on Saturday. The Nittany Lions are ranked 25th in the latest USA Today coaches poll. (The AP poll is coming out a little later than usual Sunday).
Michigan is now a member of the Top 10, as the Wolverines improved from 12th to No. 10 after beating Northwestern.
Other league teams are on the way up as well. Wisconsin, which was idle, managed to jump over Stanford to move into the No. 4 spot in the coaches' poll. The Badgers got a first-place vote for the second straight week, though Bret Bielema isn't telling whether that's his ballot. This could end up being important, since the coaches' poll is part of the formula that determines the BCS title game
Michigan State, despite not playing on Saturday, moved up from No. 20 to No. 19 in the coaches' poll. Illinois (15th) and Nebraska (14th) each climbed a spot from last week as well.
